Original No. 1,365,537, dated January 11, 1921, Serial No. 276,149, filed for reissue filed April 15, 1922.

To all whom it may concern:

Be it known that I, IVILLIAM OLEARY, a citizen of the Irish Free State, residing at Belvedere College, Dublin, Ireland, have invented a new and useful Clock, of which the following is a specification. 7

My clock is of the known type in which an impulse is timed and given to the pendulum periodically, for example every minute, by means of a roller at the end of a pivoted lever falling on a pallet fixed to the pendulum.

In order that from the outset my invention may be clearly understood I show the principal phases in the operation of this principle in Figure l of the accompanying drawings.

A pallet l is fixed transversely on the pendulum 2. An impulse lever 3 pivoted at 4 has a roller 5 which falls nominally every minute on the pallet, just a little before the pendulum reaches its median or exact minute position. In position I the impulse lever has just been released. In transition from position I to II the roller merely rolls on the pallet. In position II the edge of the pallet has reached the roller, and this latter will roll down along it,'thus giving an im-' pulse to the pendulum. In position III the roller has fallen free of the pendulum, and it will be reset for the next impulse.

My clock is also of known type inasmuch as it embodies a device for letting fall and resetting the impulse lever. And it is alsoof known type inasmuch as it embodies an auxiliary timing clock for correctly timing the release of the impulse lever.

But whereas other timing clocks synchronous with the pendulum orate mechanism operating on their going rate, I neglect all correction of the going rate of my timing clock, and substitute a much simpler method of timing. And whereas timed impulses of the kind I have described have so far been alpplied only to pendulums I apply them aso to balance wheels.

To keep my description clear I refer at first. only to the combination with a pendulum, and I shall suppose that the pendulum beats seconds and that the impulse is to be given every minute, though in practice any are kept by elabconvement period may be chosen.

The principle of my timing devlce is the fol lowing:

may have an error of several seconds in a few hours, its error in a short run like 59% seconds, though it may vary, will always remain very small. And hence if a device for releasing the impulse lever be constructed in such a way that it starts starting 7 or initial position at the exact minute, and is carried forward by the movement of such a clock to a releasing position in 59 seconds, then every run starting from the initial find the device in the releasing position i second before the next exact minute, within a. very small margin of error. The error of the timepiece may be cumulative, but that of the correctly started release is not.

from a standard position at an exact minute will piece or other suitable timing and driving device. I construct and arrange the release device in such a way that it starts from the standard starting or initial position at the moment of an impulse, and arrives at the releasing position a determined convenient fraction of a second before the next impulse period. The impulse lever is released, the impulse given, and the impulse lever reset as hereinbefore described. At this impulse the release device is restarted from initial position and times the next impulse as before.

To substantially carry is clear that the release device need not necessarily be brought to the starting position at the impulse moment, it might be trued, for example, at the resetting of the impulse lever, or at any other convenient moment, provided it is definitely fixed and closely determined by the impulse moment.

Nor is it strictly necessary, though it may be advisable, that the release device should be started true from the starting or initial position at each and every impulse. It might be trued only when the error in the run had reached a certain magnitude.

In order that my said invention may be understood I append hereunto one sheet of drawings.
